The primary purpose of this study is to determine if high doses of radiation using proton beam can be given safely with low and acceptable side effects. This study will also gather data to determine the ability of the proton beam to eradicate prostate cancer. Proton beam radiation is a very accurate kind of treatment that has been shown to affect less normal tissue than a regular radiation beam.

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • To assess the late morbidity of 82 GY delivered to the prostate and surrounding tissues using proton beam radiation [ Time Frame: 3 years ]

Secondary Outcome Measures:
  • To assess the acute morbidity following protocol treatment and to determine the ability of this treatment to control cancer. [ Time Frame: 3 years ]

Enrollment: 85
Study Start Date: February 2004
Primary Completion Date: March 2006 (Final data collection date for primary outcome measure)
Intervention Details:
    Radiation: Proton Beam Radiation
    Once a day, 5 days a week (Monday-Friday), for 8 weeks.
Detailed Description:
  • Radiation therapy to the pelvis and prostate will be given once a day, 5 days a week (Monday-Friday), for 8 weeks. Each treatment takes about 10-20 minutes.
  • Participants will be seen once a week for the entire 8 weeks by their study doctor to monitor and record any side effects. At the end of radiation therapy, participants will have a history and physical examination. Follow-up visits with the study doctor will be done at weeks 13 and 26 and then every 6 months for 3 years, then annually to year five.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

  • Zubrod status 0-1.
  • No evidence of distant metastasis.
  • No evidence of other cancer. Prior malignancy does not exclude the patient if disease free for greater than five years.

Exclusion Criteria:

  • Clinical stages T2c or above.
  • PSA greater than 15.
  • Any patient with T1c disease, a PSA less than or equal to 4 and Gleason sum less than 6.

  • Previous prostate surgery to include: simple prostatectomy, TURP, hyperthermia and cryosurgery.
  • Previous prostate radiation.
  • Prior hormonal therapy.
  • History of inflammatory bowel disease even if currently inactive or controlled on medication.
  • Prior systemic chemotherapy.
  • History of proximal urethral stricture requiring dilatation.
  • Current and continuing anticoagulation with Coumadin or equivalent.
  • Major medical or psychiatric illness
